Nobody can throw an anniversary party like the folks at Pebble Beach. To celebrate 50 years of the Ferrari 250 GTO, the world's most famous classic car show convened an incredible collection of Enzo's most coveted creation. And what a gathering it was. More than half of the 39 250 GTOs in existence were on display – the official number quoted was 22, although we could only count 21. The line of cars literally stretched farther than our cameras could capture. Factoring in the going rate of $25 million for a 250 GTO, the collection of Ferraris represented more than half a billion dollars worth of Pininfarina sheet metal and V12 engines.

Some of the more notable 250 GTOs present:1961 Ferrari 250 GT Sperimentale, chassis 2643GT: This is regarded as the 250 GTO prototype, being the first Ferrari to combine the 250 SWB chassis and the race-spec 3.0L V12. The car raced at Le Mans in 1961 and at Daytona in 1962 with Stirling Moss behind the wheel.

1962 Ferrari 250 GTO, chassis 3223GT: This is the first official 250 GTO built. The car has several distinctive features including mis-matched headlights that were thrown on the car during a race at Daytona to help the drivers see the wall on the banking at night. This car was selected as the best in class.

1962 Ferrari 250 GTO, chassis 3705GT:This 250 GTO has one of the best racing histories, finishing first in class at the 1962 24 Hours of Le Mans, second overall. The car won every race it entered in 1965.
